Strikethrough (extension)

GFM enables the strikethrough extension, where an additional emphasis type is available.
Strikethrough text is any text wrapped in two tildes (~).

Example 491

Markdown	HTML	Demo
~~Hi~~ Hello, world!	<p><del>Hi</del> Hello, world!</p>

As with regular emphasis delimiters, a new paragraph will cause strikethrough parsing to cease:

Example 492

Markdown	HTML	Demo
This ~~has a new paragraph~~.	<p>This ~~has a</p> <p>new paragraph~~.</p>
